Self-retaining adsorbent unit

Abstract

An adsorbent unit including a porous container having first and second end portions, adsorbent in the container, a rigid clip on the first end portion for engaging the spaced pipes of a U-bend of a refrigerant accumulator, a tab on the second end portion, and an aperture in the tab for receiving the filter housing on the return bend of a U-shaped pipe.

What is claimed is:  
     
       1. An adsorbent unit comprising a porous container having first and second end portions, adsorbent in said container, a rigid clip bonded to said first end portion, a tab on said second end portion, and an aperture in said tab. 
     
     
       2. An adsorbent unit comprising a porous container having first and second end portions, adsorbent in said container, a rigid clip on said first end portion, a tab on said second end portion, and an aperture in said tab, said clip including two arms having outwardly facing concave inner sides. 
     
     
       3. An adsorbent unit as set forth in claim  1  wherein said clip includes two arms having inwardly facing concave inner sides. 
     
     
       4. An adsorbent unit comprising a porous container having first and second end portions, adsorbent in said container, a rigid clip on said first end portion, a tab on said second end portion, and an aperture in said tab, said clip including clamping members at its outer ends. 
     
     
       5. An adsorbent unit comprising a porous container having first and second end portions, adsorbent in said container, a rigid clip on said first end portion, a tab on said second end portion, an aperture in said tab, said clip including two facing sections, and clamping members at the outer ends of said two facing sections. 
     
     
       6. An adsorbent unit as set forth in claim  5  wherein said two facing sections are connected by a living hinge at one of said outer ends. 
     
     
       7. An adsorbent unit as set forth in claim  6  wherein said clamping members are substantially in the shape of cylinders. 
     
     
       8. An adsorbent unit comprising a casing, first and second end portions on said casing, adsorbent in said casing, first means on said first end portion for attachment to the return bend of a U-shaped pipe, and rigid clip means on said second end portion for attachment to spaced pipes of a U-shaped pipe. 
     
     
       9. In a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent said bottom wall and with first and second pipes extending from said return bend within said housing, and a filter body extending outwardly from said return bend, the improvement of an adsorbent unit comprising a porous adsorbent container, adsorbent in said container, first and second end portions on said container, a tab extending outwardly from said first end portion of said container, means on said tab for attachment to said filter, and rigid clip means on said second end portion for attachment to said first and second pipes. 
     
     
       10. In a refrigerant accumulator as set forth in claim  9  wherein said rigid clip means includes two arms having outwardly facing concave inner sides. 
     
     
       11. In a refrigerant accumulator as set forth in claim  9  wherein said rigid clip means includes two arms having inwardly facing concave inner sides. 
     
     
       12. In a refrigerant accumulator as set forth in claim  9  wherein said rigid clip means includes clamping members at its outer ends. 
     
     
       13. In a refrigerant accumulator as set forth in claim  9  wherein said rigid clip means includes two facing sections, and clamping members at the outer ends of said two facing sections. 
     
     
       14. In a refrigerant accumulator as set forth in claim  13  wherein said two facing sections are connected by a living hinge at one of said outer ends. 
     
     
       15. In a refrigerant accumulator as set forth in claim  14  wherein said clamping members are substantially in the shape of cylinders. 
     
     
       16. In a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent said bottom wall and with first and second pipes extending from said return bend within said housing, and a filter body extending outwardly from said return bend, the improvement of an adsorbent unit comprising a porous adsorbent container, adsorbent in said container, first and second end portions on said container, a tab extending outwardly from said first end portion of said container, an aperture in said tab receiving said filter, and a rigid clip on said second end portion attached to said first and second pipes.
